Apparatus and method for protection against appliance leaking

Abstract

A water protection system apparatus for detecting and stopping a flow of water which includes a power supply, a water ionization switch, and a controlled valve assembly. The water ionization switch selectively conducts electricity when exposed to water and includes an initially dry non-conductive crystallized compound. The compound ionizes when exposed to water to form an electrolyte which conducts electricity. This switch is connected to a controlled valve assembly to stop the flow of water in response to the detection of water by the switch. Other refinements include modifications to the switch housing and condition indicators for monitoring the system and signaling water detection and shutdown operations.

Description

[0001]This application claims benefit as a continuation in part of U.S. patent application Ser. No. 09 / 546,489 filed Apr. 10, 2000 now abandoned entitled “Apparatus and Method for Protection Against Appliance Leaking” which is hereby incorporated by reference.[0002]Be it known that I, John K. Hewitt, a citizen of United States, residing at 2610 Chase Lane, Murfreesboro, Tenn. 37130; Ronald Andrew Cina, a citizen of the United States, residing at 2606 Chase Lane, Murfreesboro, Tenn. 37129; and Ronald August Cina, a citizen of the United States, residing at 1615 Lake Marina Drive, Hixson, Tenn. 37343 have invented a new and useful “Apparatus and Method for Protection Against Appliance Leaking.”BACKGROUND OF THE INVENTION[0003]The present invention relates generally to plumbing systems or devices utilizing water connections. More particularly, this invention pertains to general appliances that utilize water connections that are subject to breakage. The invention has utility in applicat...

AI Technical Summary

Problems solved by technology

All other known or patented devices use systems that are more complex or expensive.

A weak electrolyte conducts electricity, but not very well.

Thus there is nothing to transfer electricity through the solution.

These devices utilize low voltages as a safety feature and thus, these devices can be fooled by varying trace levels of elements in the water, such as calcium and iron.

In addition, main power supply fluctuations and electrical noise will also affect the reliability of these devices.

This device is designed to avoid problems associated with overflows because of clogging of the drain lines but does not address the need to shut off water coming into the machine.

These systems fail to disclose adequate systems for efficient, low-cost water detection systems for household appliances and other water utilizing systems.

Therefore, because of the inadequate systems presently used in the prior art an improved water detection system is required.
